Title:
レンズ保持用治具及びレンズ製造方法
Document Type and Number:
Japanese Patent JP6572166
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lens holding jig which can reduce a lens processing cost.SOLUTION: A lens holding jig 1 is so configured that a face facing a lens L has at least a first face 11, and a second face 12 which is not present on a surface same as the first face 11. Although a space may be generated between the first and second faces and a convex of the lens L, except the portions which support the lens, a space between the lens and the convex becomes smaller compared with a conventional blocking ring having a constant thickness dimension, and the lens L can be reliably held by the lens holding jig 1. Therefore, a lens processing cost can be reduced compared with a conventional example in which a blocking ring, of which an inner peripheral edge 14A is caused to be coincident with the convex of the lens L, is separately produced.SELECTED DRAWING: Figure 1
